Ah, I seem to be in a spot of bother with my newest VT, Gulliver. I noticed a tiny bit of redness on one of his tail tips and a small tear. It started to get a bit better but then I have turned on the light thismorning and he has made it a lot worse it seems, and a lot more red tail-tips too.

I am going to suspect that it is my driftwood and he might be bumping and scraping into it during the night. Will definitely re-assess that situation and sand it down heaps more. I have ruled out fin-rot too, his tail tips are just a bit black it seems. Im not sure if its tail biting. And I hardly think it is his plants at all (which are all live plants)

Ah, I had not considered that at all. Is stress coat the equivalent of water conditioner with Aloe and all that Jazz? We do sell API products here in AUS but would the water conditioner I currently have be just as effective? The descriptions seem to sound the same.

Stresscoat is also a good conditioner. I don't know that there's enough aloe to mean anything. It works on mammals. The most important feature is that it detoxifies ammonia for a short time. But, then so do Prime, AmmoLock, Amquel and others.

Hmm, yeah I guess it must be tail biting. What do you mean by "Filter too high"? As in too high a power or too high up the tank? I don't think I have much control over the filters power Im fairly certain.

Is your filter baffled? Bettas have such long fins many of them need the outflow baffled. You can use a water bottle baffle or rubber band a piece of sponge over the outflow. If you have a filter (that isn't a sponge filter) and your guy is tail biting, the most likely suspect is the filter current is too high. He's likely biting to cut down on drag
